A federal district judge on Nov. 4 ordered Kansas to allow same-sex couples to marry.
However, Judge Daniel Crabtree delayed enforcement of the order until next week to provide the state time to appeal.
Crabtree issued a preliminary injunction barring Kansas from enforcing its constitutional ban starting at 5 p.m. on Nov. 11.
The American Civil Liberties Union sued to overturn Kansas' ban after the U.S. Supreme Court refused to hear appeals from five states seeking to save their gay marriage bans. Among them were Oklahoma and Utah, which are in the same appeals court circuit as Kansas.
The ACLU says denying the couples it is representing the right to marry, even for a short period, would do them irreparable harm.
